Murrina-VIEW CAMERA.

Specification of Letters Patent.

Application led November 26, 1919.vv Serial No. 340,723.

T o all wimmelt may concern:

Be it known that I, J AMES W'. ANDERSON, ay citizen of the United States, residing at San Francisco, in the county of San Fran-V cisco and State of California, have invented new and useful Improvements in Multiple- View Cameras, specification.

This invention relates to multiple view cameras of the dr' plate type, Awherein a horizontally shiftable frame carries a of which the following is a plate holder,`the latter being mounted for `portion ofthe sensitized surface for exposure. on the return movement of the shift-y able frame. The shiftableframe is given a'n intermittent movement which is timed in relation to the movement of a rotary shutter f `so that when the aperture in the latter uncovers the sensitized plate, the said plate is stationary. Y

It is the object of the present invention to simplify and improve the construction and operation of a camera of this type.

n One` form which my invention may assume is exemplified in the following specification and illustrated in the accompanying drawings, wherein:

, Figure 1 shows a front elevation of the camena. with the front side thereof removed. Fig. 2 shows a rear elevation of thesame Fig., 53 shows a horizontal sectional view taken n the line 3-3 of Fig. 1. 3 s

Fig. 4/shows a side elevation of the horizontallyY shiftable frame which .carries v also a vertically movable frame to receive `the plate holder. l l

Fig. 5 shows a' side elevation of a toothed rack used in connection -with the esca ement mechanism for the vertically movable frame. i

Fig. shows a side elevaton -of the vertical slidable frame. i

The camera'as shown in Figs- 1 and 2 comprises a suitable box or casing ,2 having a front 3 to which is attached a lens 4 or others suitable, camera apparatus. A re. movable back v5 is slidable in guides 6 and hasa focusing aperture or window normally closedby a ,slide T. Withinthe box behindl .sensitized dry plate.

the lens is a rotary shutter -8 through which light may pass intermittently from the lens to a sensitized plate at the rear thereof. The shutter is preferably journaled upon a shaft secured to a vertical wall or partition 9 in the box, said wall dividing the box longitudinally, Formed in said wall is an aperture 10, which is controlled by means of Patented Feb. 22, 1921.

vertical slide 11. Immediately in the rear of the partition wall 9 is a reciprocating carriage mechanism comprising a. laterally sliiftable frame 12 x'slidable on horizontal rails or guides 13 at the to 'and bottom of the housmg and operated by driving mechanism hereinafter described. A vertically slidatle frame 15 is earrieaby the shifting frame V12 and removably receives a plate holder 16, the latter adapted to contain a The vertical dimension of the. plate holder frame is such that it may, be elevatedbodily to the upper portionA of the carriage framefso that the bottom v e o'e of the sensitized plate within the holder becomes approximately even with the bottom of the aperture 10 in the wall 9.

At the front of the carriage frame is a ver tical toothed rack 17 detachably held thereon by means of a. projection 18 at the` lower end' entering an aperture in the bottom of the frame and the upper end entering aslot, in a horizontal bar 20gxed upon .the carriageframe intermediate thetop and bottom thereof. A spring clipl 21 onthe bottom of the carriage frame has a'lug to enter an opening 22 lin the projection 18, and serves to hold the toothed rack in place.

The plate-holder frame 15 has on its lower portion a slidable bar 27 carryin at each end -an inwardly directed lug or etent 28. Thespacing of the detents is equal to the i width of the rack and one tooth', and at each isl :a flange 29 fixed tothe partition wall 9 and which is adapted to be eng lug 30 on thc slidable bar 27, w ereby the ged bya latter is shifted in a direction to release one of the detents from its tooth and allow the plate-holder and frame to drop down` wardly until the detent on the opposite side strikes av tooth.` Thereby' the plate-holder frame is lowered the distance of one tooth at each end of movement of the carriage.

Slidablcl over the front of the plate-holder I so as to eifectually cover the sensitized plate within is a slide 31- which may be lockedv in catch 3'2 for this purpose.

closed posit-ion by a suitable catch 32. The plate holder with the slide in place is placed within the frame 15 and fastened therein by means of a hinged ange 33 formed on one of the vertical. channel-shaped guides ot the frame 1:2.- Thereat'ter the-.carriage mech` anism is moved to the left-hand side ot' the housing and plate-holder and vertically slidable frame are raised to the upper limit of their movement. An endless chain 31 is positioned at the left end of the housing and carries a bifurcated member 35 so positioned as to be engaged vby alug 36 on the slide 31. The said bifurcated member has a hookshaped lower end to engave beneath the lrVhen the plateholder has been raised vvto its upward limit of movement it will be held in positionby means of the toothed bar 1T and detents 2S. The catch 32 which holds the slide in place is then released by means (j a cam 3T. and thereupon the :lide may be lowered `by operating the chain 3l. which for this purpose has a handle 3S disposed outside of the housing. Thereafter as the carriage mechanism is reciprocated lthrough suitable operating mechanism the plate-holder will be successively lowered from tooth to tooth through the escapement. mechanism already described. On account of the detachability of thetooth'ed rack 11T other racks having a different number of teeth may be readily substituted whereby to divide the sensitized plate into different spacings for the accommodation of a greater or lessV number of horizontal rows of exposures.l

The operating mechanism for the shiftable frame 1:? comprises a driving sprocket wheel 3S journaled outside `the housing and driven by a hand-crank or motor. A. spiocket chain 39 connects the said wheel 3S with a ily wheel 40 journaled within the housing. A connecting rod 11 extends from the Hy wheel 10 to a rock arm 12. which latter. through suitable pawl and ratchet meehanism. imparts an intermittent movement to a sprocket wheel 13. Spaced horizontally from the sprocket wheel 13 is a similar wheel -1-1 and over both of said wheels a chain 15 is arranged. This chain l5 has a laterally extending pin or lug 46 on its rear side working in a vertical slot 1T formed in a vertical pose or bar 4S fixed to the Shiftable frame 1:2. Thereby as the chain -15 is driven. the said frame 12 is carried along therewith step by step from one end of the camera housing to the other. second sprocket wheel 44 positively and for this purpose I show a .rock arm -19 mounted upon the shaft of said sprocket wheel 14 and carrying suitable pawl mechanism to intermittently actuate a ratchet on the shaft of said wheel. This rock arm 19 is operated by means of a connecting rod 50 which extends to the rst mentioned rock arm 4:2. I show I prefer to drive the j on the shaft of the Second sprocket wheel -11 a crank arm 51 to which is connected a rod 52 extending through the end of the housing and formed at its exterior end with a handle. This crank arm 51 has a awl to engage the ratchet wheel on the shaii of said Isprocket wheel and thereby the vsaid sprocket wheel may be actuated by hand by reciprocating the rod 52. y This is advantageousl where it is desired to shift the position of the frame 12 a slight distance. tiy wheel 10 increases the momentum of the operating mechanism so that the pawl and ratchet feed may be operated without too much of a jerk.

The shutter S is shown as driven by a.

chain 53 from a sprocket wheel on the shaft of the fly wheel 10. Thereby. it is obvious that the operation ot' the shutter and shiftable frame 12 may be so timed that when the aperture in the shutter luncovers the lsensitized plate. the said frame 12 will not be in motion. the rock arms 12 and 19 at this time being on their back stroke. The opening of the shutter S is made adjustable by providing a movable segment 53 formed on its inner end with an arcuate plate 51 cooperating with a thtmib screw 55. the latter being comiected to the shutter proper. By slacking the thumb screw. the movable segment 53 may be turned to partially or entirely close the aperture in the shutter.

Thef Provision. of the" The aperture 1 0 behind the shutter is. of.l

course. adjustable as to height by`means of the slide 11. I provide additional means whereby the width of this aperture may be y adjusted. said means comprising a pair of horizontally slidable plates 56. The lower end of the slide 11v carries a plate 5T stepped at`l each end and graduated. This stepped and graduated plate provides a convenient' means for adjustingl the plates 56 so that one willnot be opened or closed more than the other.

Cameras of this type are extensively used 4for portrait work. the advantage being that a serles of di'erent poses are then photographed quickly. which insures a better.

anismfor the plate' holder and without in any way exposing the sensitized plate to the light. In this way the subject becomes accustomed to the clicking of the machine. and having been assured thathe is not being photographed as yet, he becomes more natural in his position. Then when he is at ease, the operator presses' a bulb unbeknown to the subject and thecamera starts photographing. ,This is done bv cutting-away the upper portion of the flange 29 at the right-hand Iside of the machine when viewing the`latter from the front. This portion,

lwhich is indicated by the numeral 29, is

hinged so that it may be swungv u p to miss thelug 30 on theescapementmechanism- In this connection, it shouldbe understood that the racks 17 are so made that the upperinost tooth is on the left-hand side thereof, and therefore to lower the plate-holder theescapement mechanism must be vshifted the right-hand side lof the machine.

to the left by contact with the flange 29Tlat e hinged portion 29. is held in raised posi tion by means of a pin 58 extending through a slot' in the. partition wall 9 and formed on the end kof a plunger 59, which plunger is operated by va pneumatic bulb 60. Pressure on the bulb forces the plunger outwardly and drives the pin 58 from under the hinged member, allowing the latter to drop down and form an obstruction for the escapey ment mechanism whereby to operate the lat'- ter. The same bulb 6@ also controls a lens shutter 61 after the manner ofordinary ca meras, so that no llight is admitted through the lens until the hinged member 29* is dropped into place to release the escapement mechanism. p

Various changes in the construction and v arrangement of the several parts may be employed without departing from the spirit of my invention as disclosed in the appended claims.
